# Gaussianization for fast and accurate inference from cosmological data

@article{Schuhmann2016GaussianizationFF, title={Gaussianization for fast and accurate inference from cosmological data}, author={Robert L. Schuhmann and Benjamin Joachimi and Hiranya V. Peiris}, journal={Monthly Notices of the Royal Astronomical Society}, year={2016}, volume={459}, pages={1916-1928} }

We present a method to transform multivariate unimodal non-Gaussian posterior probability densities into approximately Gaussian ones via non-linear mappings, such as Box–Cox transformations and generalizations thereof. This permits an analytical reconstruction of the posterior from a point sample, like a Markov chain, and simplifies the subsequent joint analysis with other experiments. This way, a multivariate posterior density can be reported efficiently, by compressing the information… Expand

Posterior inference unchained with EL_2O

- Mathematics, Computer Science
- ArXiv
- 2019

It is argued that stochastic KL divergence minimization used by MCMC and VI is noisy, and EL_2O, expectation optimization of L_2 distance squared between the approximate log posterior q and the un-normalized log posterior p is proposed, which provides a reliable estimate of the quality of the approximating posterior and converges rapidly on full rank gaussian approximation for q and extensions beyond it.
